My friend yesterday was flippin dust remover upside down and spraying in on his hand because its cold. I was sitting right next to him playing my xbox 360 and I took a breath and I inhaled the vapors from the dust remover. It gave me a head ache and made my throat feel really weird. Would this cause me any pernament damage to my body or effect my wellbeing?

The warning on the back of the can says that after inhalation, get fresh air. If symptons (headache and tight throat) persist for more than a few hours, then see a doctor.
